SPECIFICATION forming part of Letters Patent No. 654,959, dated Jury 31, 1906.

Application tied April 2, 1900.

To all wwm it mayconccra:

Be it known that I, LOUISV DRVON, a citizen of the Republic of France, residing at Pont-de-Beauvoisin, (Savoie,) "France, have invented certain new and usefulflmprovements in Bottle-Stoppers for Aerated Beverages, of which the following is a speciication;

My invention relates to bottle-Stoppers for use with aerated beverages, and has for its object to provide a stopper whereby the operation of bottling is facilitated without loss of gas of the liquids, while the rapidity with which the reclosing of the stopper can be effected prevents tlie loss of gas which takes place each time it is removed.-

In order that my invention may be readily understood and carried into effect, I will describe the same fully with reference to the accompanying drawings, in which- Figure l shows a vertical central section of a bottle-stopper constructed in accordance with my invention, and Fig. 2 a modified construction of the same. Fig. 3 shows in ele-, vation and plan an appropriate device for use in connection with my improved stopper, whereby a portion of the contents of the bottle may be abstracted without entirely removing the stopper fromthebottle.

Referring more particularly to Fig. l, the main portion Rof the stopper is constructed of porcelain, glass, metal, or other suitable material and is provided with a central vertically-disposed aperture S, terminating into a flared opening A at the top of the stopper, and is contracted near the top to form a shoulder or valveseat S', which is engaged by a ball-valve B, preferably of caoutchouc or the like. This ball is constantly pressed against the narrow opening at the top by means of a helical spring C, which rests upon a pin D, arranged in the stopper at the lower portion thereof. A rubber ring or band E covers the apertures of the passage in which the pin D is located, and thus also insures a tight t between the mouth of the bottle and the stopper.

I may, if found desirable, provide a iexible washer F above the valve B, as shown in Fig. 2, so that by means of the internal pressure, combined with that of the ball, the outlet may be more completely closed.

The stopper is secured to the neck of the Serial llo. 11,128. (No model.)

bottle by means of a suitable galvanized wire or other device, such as is now commonly in around which a wire is passed having diametrically-opposed loops to engage an ordinary wire lever.

In order to .fill the bottle, it is only neces; sary to slightly open the vertical central aperture S by depressing with the aid` of the filling-nozzle the valve B or washer F. The liquid then enters the bottle, and after having lled the same the pressure from the nozzle against the ball is released, so as to allow the spring C to press the valve tightly against its seat, so forming a close and hermetic joint.

When it is desired to remove the entire contents of the bottle, the stopper is swung to one side in the manner usual with beer; bottles furnished with such lever-Stoppers.

.The closing of the bottle is effected by reversing the operation. By the use of my improved stopper it is possible tolempty the bottle or removeu any portion of the contents thereof without entirely removing the stopper. ,This may be eifected while the bottle is in an inverted position by exerting pressure against the closing-valve for the whole time during which it is desired to remove any portion ofthe contents. tained by the aid of the spring-presser (shown in Fig. 3) or by any other convenient means. If the said spring-presser be employed, it is placed across a glass or other vessel and the elastic valve of the stopper. is depressed by the projection H, when the liquid will at once be projected into the glass. As soon as sufficient liquid has been poured out the down pressure is released and the stopper closes automatically without having permitted the gas to escape owing to the inverted position.

What I claim is 1. In a bottle-stopper, the combination of the main portion R provided with a centrallyarranged vertical opening and a horizontallyextending recess, a valve-seat arranged in the said vertical opening, a spring-actuated valve adapted to engage said seat, means This result may be ob- IOO mounted in said horizontal `recess. for sup-Y portingsaid valve Aand a ieXible bandsurrounding the stopper and inclosing said horizontal recess, substantially as described.

2. In a bottle-stopper, the combination of the main portion R provided With a centrallyarranged vertical'openin'g and 'horizo'ntally extending recess, a'valve-seat arrangedin the said vertical opening, a spring-actuated valve. adapted to engage said seat, a pin arranged in the said horizontal recess to support said Valve, and a bandsurronnding the said stopperinelosing the said recess, substantially as described.
